Hi,
I have a requirement to display the parameter values in a particular order.
The folowing values (EDI_PARTNER_CD) should be displayed in the dropdown list first and then the remaining values should be sorted in ascending order:
---------------------------
INTTRA
GTNEXUS
DAKOSY
DAMCO
DBH
BMW_CONT
CATERPILLAR
CARGOSMART
EXPEDITORS
--------------------------
I need to amend the existing sql code which is used for displaying the values to incorporate the above requirement:
SELECT DISTINCT EDI_PARTNER_CD
FROM MG_EDI_PARTNER
UNION
SELECT '(NULL)' AS Expr1
FROM MG_EDI_PARTNER AS MG_EDI_PARTNER_1
WHERE (DELETED_FLG = 'N')
Any suggestions would be deeply appreciated.
Thanks.

Try adding an ORDER BY clause at the end like this:
ORDER By CASE EDI_PARTNER
WHEN 'INTTRA' THEN 1
WHEN 'GTNEXUS' THEN 2
...
WHEN 'EXPEDITORS' THEN 9
ELSE 10
END
, EDI_PARTNER_CD
Idea is, you have a two-tiered ORDER BY. The first tier will sort any of the entries in the reserved list first, followed by the rest sorted normally.

I tried to implement your code as below but getting the following error -
ORDER BY items must appear in the select list if the statement contains a UNION, INTERSECT or EXCEPT operator.
I think this is due to the UNION operator.
SELECT DISTINCT EDI_PARTNER_CD
FROM MG_EDI_PARTNER
UNION
SELECT '(NULL)', EDI_PARTNER_CD
FROM MG_EDI_PARTNER AS MG_EDI_PARTNER_1
WHERE (DELETED_FLG = 'N')
ORDER BY CASE EDI_PARTNER_CD WHEN 'INTTRA' THEN 1 WHEN 'GTNEXUS' THEN 2 WHEN 'DAKOSY' THEN 3 WHEN 'DAMCO' THEN 4 WHEN 'DBH' THEN 5 WHEN 'BMW_CONT'
THEN 6 WHEN 'CATERPILLAR' THEN 7 WHEN 'CARGOSMART' THEN 8 WHEN 'EXPEDITORS' THEN 9 ELSE 10 END, EDI_PARTNER_CD
Do you know how this can be resolved ?
Thanks.

Just wrap it in a CTE:
; WITH cte AS
(
SELECT DISTINCT EDI_PARTNER_CD
FROM MG_EDI_PARTNER
UNION ALL
SELECT TOP 1 '(NULL)', EDI_PARTNER_CD
FROM MG_EDI_PARTNER AS MG_EDI_PARTNER_1
WHERE (DELETED_FLG = 'N')
)
SELECT EDI_PARTNER_CD
FROM cte
ORDER BY
CASE EDI_PARTNER_CD WHEN 'INTTRA' THEN 1
WHEN 'GTNEXUS' THEN 2
WHEN 'DAKOSY' THEN 3
WHEN 'DAMCO' THEN 4
WHEN 'DBH' THEN 5
WHEN 'BMW_CONT' THEN 6
WHEN 'CATERPILLAR' THEN 7
WHEN 'CARGOSMART' THEN 8
WHEN 'EXPEDITORS' THEN 9
ELSE 10 END,
EDI_PARTNER_CD
As a side note: I changed UNION to UNION ALL together with a TOP 1 in order to reduce overhead (UNION is required to remove the duplicates caused by the missing TOP 1).

Do you have an underlying "master" table for these codes? If so, add a sort_sequence value to that table and sort based on that. Then you don't have to repeat it for every q -- and change it in all queries if (when) you have to modify the sort sequence.

As usual Lutz, Bang on !! Thanks very much for your help !

Thanks Scott. Will follow your advice accordingly.
